Answer:

The functions that represent this situation are A and C.

Step-by-step explanation:

A geometric sequence goes from one term to the next by always multiplying or dividing by the same value.

In geometric sequences, the ratio between consecutive terms is always the same. We call that ratio the common ratio.

This is the explicit formula for the geometric sequence whose first term is k and common ratio is r

What is the complete factorization of the polynomial below

DerKrebs [107]

Answer:

$a. \ (x-2)(x+i)(x-i)$

Step-by-step explanation:

First of all let's notice that $(x-i)(x-i)=(x-i)^2 = x^2+2xi-1 \in \mathbb{C}$ while our original polynomial is real. So we can rule out the even options B and D. At this point, if the polynomial has a factor of $(x-\alpha)$ it means tha $\alpha$ is a zero of the polynomial. Let's check both 2 (for option a) and -2 (for option c)

$p(2)=2^3-2(2)^2+2-2= 8-8+2-2=0$

$p(-2)= (-2)^3-2(-2)^2+(-2)-2=-8-8-2-2=-20$

At this point 2 is a zero, and our final factoring is a $(x-2)(x+i)(x-i)$

36 for 4 baseball hats ;56 for 7 baseball hats are they equivalent

Akimi4 [234]

No, they're not equivalent....... i suggest a calculator for this kind of math, just divide the first number by the last and compare them, like this 36/4=9, 56/7=8

the first one is $9 per hat, and the second one is $8 per hat
